First, create Web API using Azure SQL Server. Refer to part one:
Step 1
Open Visual Studio, New Project, Templates, Visual C#, Android, then select Blank App (Android).
Select Blank App. Then give Project Name and Project Location.
Step 2
Next go to Solution Explorer-> Project Name-> Resouces->layout then Right Click to Add then open new Dialog box. Then select Android Layout give name for Reg.axml after that Add New Layout Page.
Step 3
Next go to Solution Explorer-> Project Name then Right Click to Add then open new Dialog box. Then select Activity give name for NewUserActivity.cs after that Add the New Activity Class.
Step 4
Next we need add one Data Layer Class. Go to Solution Explorer-> Project Name then Right Click to Add then open new Dialog box. Then select Class give name for Login.cs after that Add New Class.
Step 5
Next go to Solution Explorer-> Project Name-> References then Right Click to Manage Nuget Packages then open new Dialog box. This dialog box to search the Json then Install the Newtonsoft.Json Packages.
Step 6
Next go to Open Solution Explorer-> Project Name->Resources->layout->Main.axml Click Open Design View. Here create Large Text, Two Plain Text and Two Buttons.
Step 7
Next to Open Solution Explorer-> Project Name->Resources->layout->Reg.axml Click Open Design View. Here create Large Text, Two Plain Text and One Buttons.
Step 8
Next to Open Solution Explorer-> Project Name->Login.cs Click Open CS code Page View then create two class name Username and Password.
- public string username { get; set; }
- public string password { get; set; }
Step 9
Next to Open Solution Explorer-> Project Name->MainActivity.cs Click Open CS code Page view then add below namespaces. Next to write given below code.
- using System.Net.Http;
- using System.Net.Http.Headers;
C# Code
- public class MainActivity: Activity
- {
- EditText txtusername;
- EditText txtPassword;
- Button btncreate;
- Button btnsign;
- protected override void OnCreate(Bundle bundle)
- {
- base.OnCreate(bundle);
-
- SetContentView(Resource.Layout.Main);
-
-
- btnsign = FindViewById < Button > (Resource.Id.btnloglogin);
- btncreate = FindViewById < Button > (Resource.Id.btnlogreg);
- txtusername = FindViewById < EditText > (Resource.Id.txtlogusername);
- txtPassword = FindViewById < EditText > (Resource.Id.txtlogpassword);
- btncreate.Click += Btncreate_Click;
- btnsign.Click += Btnsign_Click;
- }
- private async void Btnsign_Click(object sender, EventArgs e)
- {
- HttpClient client = new HttpClient();
- var uri = new Uri(string.Format("http://xamarinlogin.azurewebsites.net/api/Login?username=" + txtusername.Text + "&password=" + txtPassword.Text));
- HttpResponseMessage response;;
- client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
- response = await client.GetAsync(uri);
- if (response.StatusCode == System.Net.HttpStatusCode.Accepted)
- {
- var errorMessage1 = response.Content.ReadAsStringAsync().Result.Replace("\\", "").Trim(new char[1]
- {
- '"'
- });
- Toast.MakeText(this, errorMessage1, ToastLength.Long).Show();
- }
- else
- {
- var errorMessage1 = response.Content.ReadAsStringAsync().Result.Replace("\\", "").Trim(new char[1]
- {
- '"'
- });
- Toast.MakeText(this, errorMessage1, ToastLength.Long).Show();
- }
- }
- private void Btncreate_Click(object sender, EventArgs e)
- {
- StartActivity(typeof(NewUserActivity));
- }
- }
Step 10
Next to Open Solution Explorer-> Project Name->NewUserActivity.cs Click Open CS code Page view then add below namespaces. Next to write given below code.
- using System.Net.Http;
- using System.Net.Http.Headers;
- using Newtonsoft.Json;
C# Code
- public class NewUserActivity: Activity
- {
- EditText txtusername;
- EditText txtPassword;
- Button btncreate;
- protected override void OnCreate(Bundle savedInstanceState)
- {
- base.OnCreate(savedInstanceState);
-
- SetContentView(Resource.Layout.Reg);
- txtusername = FindViewById < EditText > (Resource.Id.txtsaveusername);
- txtPassword = FindViewById < EditText > (Resource.Id.txtsavepassword);
- btncreate = FindViewById < Button > (Resource.Id.btnsavecreate);
- btncreate.Click += Btncreate_Click;
- }
- private async void Btncreate_Click(object sender, EventArgs e)
- {
- Login log = new Login();
- log.username = txtusername.Text;
- log.password = txtPassword.Text;
- HttpClient client = new HttpClient();
- string url = "http://xamarinlogin.azurewebsites.net/api/Login/";
- var uri = new Uri(url);
- client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
- HttpResponseMessage response;
- var json = JsonConvert.SerializeObject(log);
- var content = new StringContent(json, Encoding.UTF8, "application/json");
- response = await client.PostAsync(uri, content);
- if (response.StatusCode == System.Net.HttpStatusCode.Accepted)
- {
- var errorMessage1 = response.Content.ReadAsStringAsync().Result.Replace("\\", "").Trim(new char[1]
- {
- '"'
- });
- Toast.MakeText(this, errorMessage1, ToastLength.Long).Show();
- }
- else
- {
- var errorMessage1 = response.Content.ReadAsStringAsync().Result.Replace("\\", "").Trim(new char[1]
- {
- '"'
- });
- Toast.MakeText(this, errorMessage1, ToastLength.Long).Show();
- }

I am getting unhandled exception error at response = await client.GetAsync(uri);

Hi Anbu, thanks for your articles. However I still get the error message as others are commenting; {"$id":"1","message":"No HTTP resource was found that matches the request URI . I checked my routing and I am not using localhost. Do you have any suggestions what to do?
Wendell RamosPosted Feb 26, 2018, 12:07 AM
What if the API is self hosted? like WPF api, but its still a xml/json file. What i want sir is, how can i make the validation from the application? Not from the Azure app. How to make own validation from android. Thanks in advance :)

Hi Anbu Mani I have the same problem: if I try to create a user by code, I get an error that no Http resource was found that matches the request uri...Even though I'm choosing the same url for both POST and GET, seems like in the Post request, the parameters are not being sent. "{"$id":"1","message":"No HTTP resource was found that matches the request URI = "xxxxxxxxxxxxxxxxxxxxxxxx"...... Whrere Check "WEB API Routing" I dont understand.. Please helpme... Thanks
Wael ElZahrPosted Jun 18, 2017, 12:58 PM
Thanks for the tutorial. The Login works well if I add a user from the db. However, if I try to create a user by code, I get an error that no Http resource was found that matches the request uri...Even though I'm choosing the same url for both POST and GET, seems like in the Post request, the parameters are not being sent. ANy ideas?
